WP2LaTeX is a program designed to translate WordPerfect documents into LaTeX 2.09 and LaTeX 2.0e. It is able to cope with Macintosh WordPerfect 1.x, 2.x, 3.x, and 4.x and PC WP 4.x, 5.x, and 6.x documents (WP 7.x and 8.x have same binary file format as 6.x, so no additional conversion module is necessary.)

eLyXer (pronounced elixir) is a LyX to HTML converter. While there are a ton of such projects all over the Web, eLyXer has a clear focus on flexibility and elegant output. LyX is a wonderful text editor that produces beautiful PDF files. Internally, it exports documents to LaTeX, and from there to PDF. Sadly there is not an equivalent “export to HTML” option. With eLyXer, you can convert your master’s thesis, learned article, fascinating novel, or love letter to an HTML page that you can then publish on the Web. It is a standalone tool that does not depend on LyX.

Midi Converter for Mac is a small and simple utility designed mostly for musicians who compose music using their computer. However, it can be very useful for anyone who wants to convert MIDI music files to MP3 or other popular formats. It is around 10 times faster than the other competing programs, because it converts the files directly rather than having to record them first. The program is very easy to use, and a trial version is available. It also allows you to embed a player, and has a number of other features. It does not rely on your sound card with regards to the quality of the final output, so you can expect high and consistent quality, regardless of what sort of computer you are going to use it on.
